AMDISP I2C device requires to power on ISP HW to probe the sensor
device. Instead of using the exported symbols from ISP driver to
control the power and clocks remotely,added Generic PM Domain (genpd)
support in amdgpu_isp device for its child devices (amd_isp_capture,
amd_isp_i2c_designware) to set power and clocks using PM methods.

Enable the cleaner shader for other GFX9.x series of GPUs to provide
data isolation between GPU workloads. The cleaner shader is responsible
for clearing the Local Data Store (LDS), Vector General Purpose
Registers (VGPRs), and Scalar General Purpose Registers (SGPRs), which
helps prevent data leakage and ensures accurate computation results.
This update extends cleaner shader support to GFX9.x GPUs, previously
available for GFX9.4.2. It enhances security by clearing GPU memory
between processes and maintains a consistent GPU state across KGD and
KFD workloads.

This commit makes two key fixes to SDMA v4.4.2 handling:
1. disable UTC_L1 in sdma_cntl register when stopping SDMA engines
by reading the current value before modifying UTC_L1_ENABLE bit.
2. Ensure UTC_L1_ENABLE is consistently managed by:
- Adding the missing register write when enabling UTC_L1 during start
- Keeping UTC_L1 enabled by default as per hardware requirements
v2: Correct SDMA_CNTL setting (Philip)

Simplify SDMA v4_4_2 queue reset and stop operations by:
1. Removing GET_INST(SDMA0) conversion for ring->me
2. Using the logical instance ID (ring->me) directly
3. Maintaining consistent behavior with other SDMA queue operations
This change aligns with the existing queue handling logic where
ring->me already represents the correct instance identifier.

This commit makes the following improvements to SDMA engine reset handling:
1. Clarifies in the function documentation that instance_id refers to a logical ID
2. Adds conversion from logical to physical instance ID before performing reset
using GET_INST(SDMA0, instance_id) macro
3. Improves error messaging to indicate when a logical instance reset fails
4. Adds better code organization with blank lines for readability
The change ensures proper SDMA engine reset by using the correct physical
instance ID while maintaining the logical ID interface for callers.

VRAM offset of each VRAM BO will be changed, and the cached gpu
addresses needed to updated.
This is to enable pdb0 and switch to use pdb0-based virtual gpu

addresses do not change, this can avoid the need to update all

2 reasons for this change:
1. when pdb0 is enabled, gpu addr from amdgpu_bo_create_kernel() is GART
aperture address, it is not compatible with SMU and PSP, it need to be
updated to use FB aperture address.
2. Since FB aperture address will change after switching to new GPU
index after hibernation, it need to be updated on resume.
